Question

how do the hadley cells operate?
the earths rotation stops air from moving poleward.
the equator repels air masses.
hot air at the equator rises and pushes down cooler air creating convection cells.
gravitational forces pull winds towards the equator

Explanation:

Hadley cells are atmospheric circulation patterns. At the equator, the sun heats the air, causing it to rise. This rising hot - air creates a low - pressure area. As the hot air moves towards the poles, it cools and sinks, pushing down cooler air and creating a cycle of convection. The Earth's rotation affects the direction of the air movement but does not stop air from moving poleward. The equator does not repel air masses, and gravitational forces do not directly pull winds towards the equator in the context of Hadley cell operation.

Answer:

Hot air at the equator rises and pushes down cooler air creating convection cells.
